4 Claims. (Cl. 51-185) This invention relates to the manufacture ofa cleaning cloth that is especially adapted for the polishing and cleaning of metal, plastic and enamel pots, pans and dishes as well as vitreous Ware as bath tubs, Wash basins, oven glassware and china.

The invention is fully disclosed in the followingdetailed description and drawings forming a part thereof in which Figure 1 is a plan view of a cleaning or pot cloth embodying a form of the invention;

Fig. 2 is a cross-section taken on the lines 2--2 of Fig. l;

Fig. 3 is a cross-section taken on the line 3--3 of Fig. 1;

Fig. 4 is a plan view of a modied form of the invention and Figs. 5 and 6 are cross-sections taken on the lines 5 5 and 6 6, respectively, of Fig. 4;

Fig. 7 is a plan view of a still further modication of the invention.

Referring to the drawings and the construction shown therein, the numeral I designates my improved cleaning cloth, the same comprising a deep pile fabric 2, preferably composed of the socalled terry cloth or Turkish towelling and having uncut pile loops 3 forming the nap thereof. Such loops are each coated with a layer 3 of plastic composition and are filled with beads 3 of the same composition, the same being desir- I.

ably sprayed thereon as the compressed air in the spray will tend to maintain the loops of the cloth upright and thus facilitate both the coating of the loop threads and the internal filling of the loops 3 themselves.

Following the spraying of the plastic composition on to the loops aforesaid, the treated cloth is baked in an oven at a sufficiently high temperature and for a suicient time to thoroughly evaporate the Water or other liquid vehicle of the spray composition and to set the solid contents thereof into an elastic, water-insoluble state or condition on the treated bers of the loops. Thereupon, the baked cloth is removed from the oven. The recovered cloth is then extended to its full length and marginal bands such as a, b, c, d, g, or h are pasted along both sides of all of its edges, preferably by a controlled dipping operation, and then if it be desired to form cleaning cloths of the forms illustrated in Figs. 1 or 7, such as the cloths I or I', the pasted cloth is folded on itself either along the fold line F (see Fig. l) or else along the fold -line F (see Fig. 7), in order to form a flap member 4 of rectangular configuration or a flap member I I I jof triangular configuration that is about.

one-quarter the size of the main body I0 of the cloth shown in Fig. 7. After being so folded, the

cloth is again baked While supplying sufficient pressure to the iiap to rmly adhesively unite the same to the underlying cloth.

In the form of the invention illustrated in Fig. 4 a separate pad member I5, formed of the same kind of treated terry cloth as that in the forms of the invention shown in Figs. l and '7, is pasted with waterproof cement along both sides of all of its edges. folded about the central fold line F" and caused to envelop the upper end of the cloth I, which latter is composed of terry cloth treated as aioresaid, after which the cloth I6 with the pad I5 applied thereto is vagain baked in the oven while applying suiiicient pressure to the pad to adhesively unite both of the sides of the same to the enveloped cloth I6.

For the plastic spraying composition I preferably employ a water solution of a urea-formaldehyde resin with which I incorporate a suitable plasticizer in the Well known Vmanner together with from about 10%. to about 25% of a finely divided abrasive ller, as for example marble dust, powdered pumice, silica dust or emery dust; as such plastic being Water-soluble any re haz- '1 ard during the drying of the spray coating applied to the fabric is eliminated. Other plastics which are somewhat elastic, such as Lucite and cellulose acetate, for example, may also be used in lieu of the aforesaid plastics.

I am well aware of the Patent No. 2,375,585 vI wherein is disclosed a plastic abrasive pad formed of water-repellant plastic. in the form of a web is folded on itself and the opposed marginal cut ends are sealed together. These pads being unaffected by water (page 2, lines 19 and 20, col. l) are incapable of drinking up Water, as do the warp and Woof of applicants pot cloth, and being thereby rendered'soft and pliable. Accordingly, applicant disclaims as f being Withouty the scope of the appended claims any such patented construction.

Thereupon, the pad element is i The plastic to pots and pans or sanitary ware. Moreover, the single edge f (see Fig. 1), the double reinforced edges g and g and the oblique reinforced edges h and h' function as extremely effective non-metallic, non-ravelling scraper members and, in the case of the Scrapers h, h', the scraping action occurs on both the forward as well as the return strokes due to their aforesaid oblique disposition.

As is appareritffrom aan. inspection thereof,the coated loop ibers and the encased beads 3 constitute knuckles, so-to-speak which of themselves serve as effective debris-removal elements during a cleaning operation with my improved pot cloth.

Since, in the construction of pot cloth shown in Fig. 4 and Fig. 5 there are two opposed'scrap'er members, it is unnecessary tmrsttobseisve-which side of the cloth is up before commencing the use of the same.

The lateral re-inforcedfedges l1, I1' (see Fig. 1)..and IB. I8', I8 (see-Eig. 6) ibe'causenfltheir short Fspan *constitute extremely :effectivefscraper members.

The .limitation of the .cemented tareas v to :the

bands extending marginally of thecloth insures i that the terry cloth component V:base bers .will remain soft, .pli-able .and .highly absorptive Lof water, morel especially soapy water and detergent solutions. So also do .thepads .formed Vof .such cloth .remain soft-.and exible.

IMy improved .cleaning :cloth is designed .for heavy .duty Work in lthecleaning of pots, pans andthe like since thefolded hap member or members materially aids in the dislodgin'g :of foodiencrustednr otherwise :obstinately adhering to the surfaces being cleaned, vparticularlysince the leadingiap edgesk which are re-inforced. and strengthened by the.y additional adhesive required to unite Iit eiectively to :the underlying .cloth constitute a relatively rigid ridgeA which: functions as a'scraper.

Among the outstanding advantages 'of the aforesaid cloth construction are the :complete absence .of vanylrnetal therein, theabilityfof the uncoated Warp and Woof of the .fabricfto .drink up Water and theeectivenessLof the plasticbeads encased in the-loops 3 for .the removal .of obstinate incrustations andthe like from fmetalz'or enamel surfaces. The flap member -has zstill another function, namely it forms a thicker pad in .the'area covered thereby and thuszadmitsof theuser applying considerably greater .pressure through the fingers .uponthe incrustation .or the likewhich it is .desired to `remove from afutensil.

One of the advantages of .the-pad disclosedfin Fig. `'I wherein the iiap is of triangular conguration resides inthe fact that the fiapradmits-:of a to-and-fro scraping action beingpossible taperform. and one of the. advantages of-.the padshown scription, the mere manipulation of a folded cloth held in the hand of a user would be wholly ineffectual for dislodging the incrustations and the like from surfaces of pots, pans and sanitary ware because, unless the fold was cemented to the underlying cloth it Would not retain its shape and furthermore as the cloth would not have any re-inforced edges it would be altogether too pliable .to be useful. Y, v

Having .thus describedthe invention, iwhat I claim and desire vto secure by Letters Patent of `Athe United States is:

As a new article of manufacture, a. cleaning 'ldth'composed of a looped fabric of the nature of .terry cloth the major portion of the warp and wocfwhereo'f ishighly pliable and water-absorpztiveandrthesnap onrat least one side thereof being in the form of separate loops which are coated andiilleliwith a soap-resistant, Water-insoluble plastic, said cloth being l"folded on itself to form a flap/element of van areaconsiderablylessithan one-half .that of the Yunderlying cloth an'd Tthe edges of the apelementbeing adhesivelyfurlite'd to Vthe `underlying `cloth Aand `being re-inforce'd with cementitious -material .to form scraper' means.
